Starting Loop: Setup
The settings that you’ll see when you first open the Loop app vary based upon which version of Loop you’ve built and which pump you use.
The LoopDocs references, below, show the setup for the Master branch.
Initial Loop Set Up and Configuration
Please review the steps in LoopDocs Set up Apps section on how to add your Pump, CGM, and Services to Loop.
There are a few additions (not yet updated in LoopDocs).
This page will be updated when LoopDocs gets updated. Please review these updates, too.
Step 3: Add CGM – update for Dexcom CGM
- Do not enter Dexcom Share creditials when you enter CGM
- If you inadvertently added them, delete your CGM and add it back with just the Dexcom Transmitter ID
Step 4: Configuration – Correction and Override Ranges
- The graphic in LoopDocs shows an old screen with a Workout Override just below Pre-Meal
- The Pre-Meal override is still found there, but other overrides have been completely reworked
- Later on, check out the Override Strategy page
Step 4: Configuration – Pre-Meal Target Override
- Some people prefer to leave this blank
- The consequence is you cannot use it (but you can still prebolus)
- The advantage is you won’t accidentally bump it and turn off an override by mistake
- NOTE – once you enter a value here – that button will always be active – so you might want to wait and see if you want to use it
Step 5: Loop Services – Nightscout
- One more plea to consider adding Nightscout
- You can use Loop without Nightscout, but should you?
- To be a great Looper with great settings, Nightscout is your best friend
For those of you who are opting for AB branch, you will notice an extra configuration switch called Dosing Strategy. You have two options- Temp Basal Only or Automatic Bolus. If you select Temp Basal Only, then Loop will behave exactly like Master. Many mentors currently helping Loopers decide which branch to build, tend to suggest AB because you can switch between Master and AB by changing that one setting; no rebuild required.
New Loopers: Skim over the next paragraph – but remember it exists if you need more flexibility later – especially if you have a Little Looper.
For those of you who are trying Jon Fawcett’s AB Strategy Switching Patch, you will have two more configuration options – Auto Strategy Switching and a Dose Switching Threshold. The Auto Strategy Switching checkbox gives you the ability to automatically switch between Autobolus and Temporary Basals. The Dose Switching Threshold determines the BG rate at which you switch from Automatic Boluses to Temp Basals. Essentially, if over the set BG value, it will use Automatic Boluses. If under the set value, it will use Temp Basals. This patch can be found in Jon’s github repository.
